Steve thanks, I must admit I'm not sure on my next move. The truck is parked but I'm not sure that's good. I'm pretty sure my machanic and I are in over our heads (no way to check and rebuild the head). the location I purchase the truck from has a guy (Porche, BMW experience) He wants to do a chemical test to make sure it's the head gasket. Do you know anything about that test? But that's a start, not just looking to ripe the head off. No warranty, 135K I'm on my own.

The truck is in great shape, looking for good repair job.
